Troubleshooting Tips

  • Can't Connect to the Internet? Double-check the DNS addresses you entered. Make sure there are no typos.
  • Still Not Working? You may need to restart your computer or reset your router.
  • Try Different DNS Providers: If you experience issues with Google or Cloudflare, consider trying OpenDNS (Preferred: 208.67.222.222, Alternate: 208.67.220.220).

Remember, if you’re unsure, it’s okay to stop and ask for help before trying again.

Expected Outcome

Once you've followed these steps, your internet connection will use secure DNS servers, which may lead to faster access to websites and enhanced privacy during your online activities.

Tip for strong passwords: Use at least 12 characters with a mix of letters, numbers, and symbols. Avoid names or birthdays.
